Questions Over Water Quality at Philly Airport

Philadelphia International Airport has lost its "approved" status for watering and aircraft servicing, the U.S. Food and Drug Administration (FDA) said in an Aug. 9 warning letter to airport executive Mark Gale.

In the warning letter, FDA put Philadelphia International Airport on "provisional" status, giving it 30 days to either regain approved status or face being listed as "non-approved" for carrier use.  In the worst case scenario, being non-approved could shut down all or part of one of the East Coast's second-tier airports.
